--split options returns weird alpha-beta split

[YAY-C]

.npy output :

<93>NUMPY^A^@v^@{'descr': '<f8', 'fortran_order': False, 'shape': (3, 6, 554), }                                                     

running: python -m qstack.spahm.rho.bond --mol list_water.txt --spin list_water_spins.txt --charge list_water_charges.txt --name tttt --split
at : Q-stack/tests/data

the first dim is the 3 molecules of waters but each of them as 3*2(alpha, beta)=6 vects with UNKNOWN SEQUENCE
